The Influence of Lorazepam upon Pre- and Poststimulus EEG during Sleep in Man

1997

Enhancement of beta power in the spontaneous EEG under the influence of benzodiazepine medication is a well known phenomenon under waking conditions as well as during sleep. On the other hand, in certain frequency bands EEG activity following external stimulation is also enhanced. Therefore, the question arises what relationship exists between pre- and poststimulus EEG under the influence of benzodiazepines. Is an augmentation of beta activity during benzodiazepine medication further enhanced when external stimulation is applied? In order to address this question we compared the spectral power of pre- and poststimulus EEG under 2.5 mg lorazepam during sleep with placebo conditions. The hypo…

The university campus environment as a protective factor for intimate partner violence against women: An exploratory study

2017

Some neighborhood characteristics linked to social disorganization theory have been related to intimate partner violence against women (IPVAW). The study of other neighborhood-level factors that may influence IPVAW risk, however, has received less attention. The aim of this study is to analyze the influence of university campuses on IPVAW risk. To conduct the study, IPVAW cases from 2011 to 2013 in the city of Valencia, Spain, were geocoded (n = 1,623). Census block groups were used as the neighborhood analysis unit. Distance between each census block group and the nearest university campus was measured. A Bayesian spatial model adjusted for census block group-level characteristics was perf…

Abdominal scintigraphy for diagnosis of intestinal bleeding

1978

Abdominal scintigraphy with99mTc-pertechnetate, using a gamma-camera linked to a data processor, was done in 8 patients with acute massive intestinal hemorrhage and in 34 patients with chronic recurrent intestinal hemorrhage. Endoscopy and x-ray studies had failed in all patients to reveal a bleeding source. All but 3 patients underwent exploratory laparotomy, confirming the abnormal findings of scintigraphy. In all acutely bleeding patients, scintigraphy was positive. The bleeding was proven by laparotomy to be due to Meckel's diverticulum with gastric mucosa in 5, jejunal neurinoma in 1, and sigmoid colon carcinoma in 1 patient. Scintigraphy was positive in only 3 chronically bleeding pat…

Psychometric properties of the Brief Symptom Inventory-18 in a Spanish breast cancer sample

2007

Abstract Objective The objective of this work was to study the psychometric and structural properties of the Brief Symptom Inventory-18 (BSI-18) in a sample of breast cancer patients ( N =175). Methods Confirmatory factor analyses were conducted. Two models were tested: the theoretical model with the original structure (three-dimensional), and the empirical model (a four-factor structure) obtained through exploratory factor analysis initially performed by the authors of the BSI-18. Results The eligible structure was the original proposal consisting of three dimensions: somatization, depression, and anxiety scores. These measures also showed good internal consistency. Conclusion The results …

Women With and Without Metabolic Disorder Differ in Their Gut Microbiota Composition

2012

The aim of this study was to investigate whether overweight/obese women in metabolic disorder group (MDG, n = 27) differ in their gut microbiota composition from overweight/obese women in non-metabolic disorder group (NMDG, n = 47) and normal weight women group (NWG, n = 11). Gut microbiota was profiled from fecal samples by 16S rRNA fluorescence in situ hybridization and flow cytometry in 85 premenopausal women. Body composition was measured by bioimpedance, and dietary intakes were collected via food diaries. Standard procedures were used to assess plasma glucose, serum insulin, lipids, and inflammatory status. We found that the proportion of bacteria belonging to Eubacterium rectale-Clos…

Psychological assessment of patients with temporomandibular disorders: confirmatory analysis of the dimensional structure of the Brief Symptoms Inven…

2006

Abstract Objective This article analyzes the psychometric and structural properties of the Brief Symptoms Inventory 18 in a sample of patients with temporomandibular disorders (TMDs), given the convenience of a brief evaluation of distress in these patients. Methods Confirmatory factor analysis was carried out in a sample of 114 patients with TMDs. Two models were tested: the theoretical model with the original structure proposed—which considers three dimensions—and the empirical model obtained through the exploratory factor analysis initially carried out by Leonard R. Derogatis—which consists of the four-factor structure. Results Both models reached satisfactory indexes in confirmatory fac…

Targeted Hybrid Nanocarriers as a System Enhancing the Skin Structure

2021

The skin is constantly exposed to external and internal factors that disturb its function. In this work, two nanosystems-levan nanoparticles and a surfactin-stabilized nanoemulsion were preserved (tested for microbial growth) and characterized (size, polydispersity, Zeta potential, and stability). The nanosystems were introduced in the model formulations-cream, tonic, and gel, and confirmed by TEM. The analysis showed that nanoemulsion has a spherical morphology and size 220–300 nm, while levan nanoparticles had irregular shapes independently of the use of matrix and with particle size (130–260 nm). Additionally, we examined the antiradical effect of levan nanoparticles and nanoemulsion in …

Intercomparison of spanish advanced lidars in the framework of EARLINET

2007

To extend and reinforce the action of the EARLINET- ASOS project, a nucleus of Spanish advanced lidars was created. Four systems were intercompared satisfactorily in terms of backscatter coefficients at two elastic wavelengths. Peer Reviewed

Valoración, afrontamiento y ansiedad a la hora de dejar de fumar

2010

El objetivo de este estudio consiste en analizar la valoración (appraisal) cognitiva y los tipos de afrontamiento que adoptan las personas a la hora de dejar de fumar. El instrumento de evaluación utilizado en una muestra de 107 estudiantes es el Inventario de Valoración y Afrontamiento (IVA), diseñado a partir del modelo de la valoración de Lazarus y Folkman (1986). El IVA consta de tres subescalas de valoración (amenaza, desafío e irrelevante) y seis subescalas de afrontamiento (cognitivo y conductual-motor dirigido a cambiar la situación, cognitivo y conductual-motor dirigido a reducir la emoción, pasivo y evitativo). Los resultados, señalan que cuando las personas realizan una valoració…
